QR Codes are the latest craze in the tech world. These codes are similar to a bar code but can hold far more information and different types of information. The idea behind this is basic. Customers can take a picture on their smart phones and automatically follow a link to your website, have your contact information saved into their phone or have coupons for the next time they shop with you. These codes can be seen on business cards, flyers, websites, or wherever you can target customers.
